I have a 2.4 dual core and it runs most games at fullspeed, with a few slowdowns on parts with high amounts of detail... Also, there are a few games that I cant get fullspeed... Of course Im talking only about the games that can be fullspeed on Dolphin.

Ya, but combined with Geforce 7000m card, which is almost 5 years old, and the last games it can run on medium details are from 1999-2005.. There is a high chance that when accompanied with older turion processor, dual core or not, it will not achieve very playable framerates. (Card also has 0mb of hardware memory and 256mb virtual vram)

That's subjective though, there is no definite answer but to try yourself. But be prepared that some games may not run well.
